Answer: The regular price of the granola bars were $5 each.

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given:

  • <em>Discount = 10% = 0.10 (decimal form, 10/100 =0.1) </em>
  • <em>Cost after discount: $4.50 </em>

So, the original price of the granola bar (x) multiplied by 0.9 ( since 100% is the full price,1- 0.1= 0.9) equals to 4.50 (cost after discount)

Mathematically speaking

x (1- 0.1) = 4.50

x 0.9 =4.50

x = 4.50/0.9

x= 5

Feel free to ask for more if needed or if you did not understand something.

Answer: The regular or normal price of the nut - free granola bars is $5.00

Step-by-step explanation:

Firstly, a discount simply refers to the reduction in the regular or normal price of a commodity or service.

In this case, Trey purchased his preferred nut - free granola bars but he did not buy the nuts at the usual price. The price or cost of the nut - free granola bars were reduced by 10 percent.

Now, let us denote the regular or normal cost of the nut - free bars as $x.

Since the original price was reduced by 10%, then:

10/100 × x = x/10 (This is 10% of the cost of the nut - free bars)

Let us now subtract 10% of the original cost of the nut - free granola bars from the regular cost of the bars. This will now be equal to the price that Trey finally purchased the bars.

x - (x/10) = $4.50

All we need to do now is to solve for "x" and we will discover the original cost of the bars.

(10x - x)/10 = 4.50

9x/10 = 4.50

9x = 4.50 × 10

9x = 45

x = 45/9

x = $5 (This is the normal price of the bars).

A company that manufactures small canoes has a fixed cost of $ 18 comma 000$18,000. It costs $ 120$120 to produce each canoe. Th
Scilla [17]
If the company makes 1 canoe only, then the cost is, the fixed cost plus how much it costs for the 1 canoe, or
180,000 + 1*120

if it makes 2 canoes
180,000 + 2*120
3 canoes   180,000 + 3*120
4canoes   180,000 + 4*120
x canoes  180,000 + x*120

so... we dunno what "x" is, but whatever "x" maybe, the cost ends up as 180,000 + x*120, or 180,000 + 120x

now, let's see the revenue
1 canoe 1 * 240
2 canoes 2*240
3 canoes 3*240
x canoes x*240

so.. whatever "x" maybe, the Revenue is x*240 or 240x

break-even point is when, the amount of expenses and earnings cancel each other out, or, there's no profit, but there's no loss either, same amount that's spent is also earned back

so, the break-even point occurs when Revenue = Cost

180,000 + 120x = 240x     <--- solve for "x"

Part of a book fell out. The first page of this part has number 143. The last page has a number written with the same digits. Ho
Gnom [1K]

Answer:

142 pages

Step-by-step explanation:

The parameters given are

First page of part of the book available = 143

The last is numbered with the digits 143

Since the book is said to have been split into two parts with, we have that one part of the book starts from the beginning, while the other part continue from the first part stops

Number on the pages on the first part = from 1 to number on the first page on the second part - 1

Hence, the part of the book available is the second part and the number of pages in the first part = 1 to 142 or 142 pages.

How do you explain to estimate 368+231 in two different ways
Ludmilka [50]
You can use the break apart strategy which would look like:
368+231= 300+60+8 + 200+30+1
Or you could just plain and simple add 368+231

The Zonda Information and Telephone Company (ZI&amp;T) calculates a customer’s total monthly cell phone
Olenka [21]

Answer:

The answer of the following question is m = \frac{C - b - bt}{r + rt}.

Solution:

C = (b + rm)(1 + t),

C = b + rm + bt + rmt

C = b + bt + rm + rmt

C - b - bt = m (r + rt)

\frac{C - b - bt}{r + rt} = m

t\neq -1,  

r\neq 0
